ELECTRIC TIME=RECORDER.

SPECIFICATION forming part of Letters Patent No. 389,626, dated Esp Application filed January 5, 1888. Serial No. 259,548. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALoYs WiRsoHINe, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in \Vatehmens Time- Detectors, of which the following is a specification.

My invention relates to time-detectors for electrical or mechanical operation; and it consists in a certain novel combination of typewheels and of a switch and switchdial with a clock-movement controlling the adjustment of both the type-wheels and the switch, whereby a record of the watch mans time may be printed on a traveling tape for insuring accuracy of such record, and whereby the stations to be visited by the watchman may be alternately brought into and out of an electric circuit controlling the printing operation for permitting such operation from certain stations only within certain intervals of time.

In the accompanying drawings, Figure 1 represents a rear view, partlyin section, ofa timepiece embodying my invention. Fig. 2 repre sents a like view thereof with some of the parts omitted. Fig. 3 represents a vertical central section thereof. Fig. 4 represents a horizontal section thereof. Figs. 5 and 6 represent detail views of parts. Fig. 7 represents a face view ofa portion of the printed tape. Fig. 8 is a diagram showing the switch-connections.

Similar letters of reference indicate similar parts.

The letter A indicates the frame of a clockmovement, which may be of any usual or suitable construction, and of which 0 is the center shaft, carrying the minutehand. On the rear end or portion of said shaft 0 are two cams, B O, which are in fixed position, so as to revolve with the shaft, and one of which, 13, has a single lobe or elevation representing one hour, while the other, C, has a series of twelve lobes, each representing five minutes that is to say, the number of lobes of said lastnamed cam is in fixed relation to the minutes of time and may be varied according to circumstances. Each of said revolving cams B O engages with one end a lever, F or G, which may be termed an hour-lever or minutelever, and on the other end of which is pivoted a spring-pawl, F or G, engaging with a ratchet-wheel, hereinafter described, both levers having their fulcra in a post, A, on the eloek-frame and being provided with a returnspring, F or G The letters D H M denote typewlieelswhich are arranged side by side on a shaft, K, having its bearings in the clock-frame, together with a bracket, A, on said frame, and one of which, D, is a day-wheel, it being in practice marked with letters or other characters indieating the days of the week, and, if necessary, also divisions thereof, while H is an hourwheel, it being marked with figures indicating twelve hours oftime, and Misa minute-wheel, it being marked with figures indicating min utes of time. The number of letters or other characters on said daywheel D is in this example fourteen, (see Fig. seven representing one half and the remaining seven the other half of each day of the week, while the number of figures on said minute-wheel M corresponds with the number of lobes of the minute-cam O, and hence is twelve, (see Fig. 1,) representing intervals of five minutes.

Each of the type-wheels D H M is firmly connected to a ratchet, D, H, or M, as more clearly shown in the sectional view, Fig. 6, the hour-wheel H with its ratchet being fixed to the wheel-sha ft K, while both the day-wheel D and ininuteavheel M with their ratchets are left loose. The pawl F of the hour-lever en gages with said ratchet H of the hour-wheel, as shown in Fig. 2, and the pawl G of the minute-lever engages with said ratchet M of the minute-wheel, so that when said levers are actuated by the cams B O the proper ratchets are in turn actuated by the pawls. Y

The number of teeth of either ratchet D H M corresponds with the number of type on the wheel to which it is conneeted that is to say, the ratchet D of the day-wheel has fourteen teeth, the ratchet H of the hour-wheel twelve teeth, and the ratchet M of the minutewheel also twelve teeth-and one of the teeth of said hour-wheel ratchet is su nken to a greater depth than the remaining teeth thereof, as at H", Fig. 2, causing the pawl F of the hourlever to take a lower or deeper position in re lation to the axis of said ratchet once in every revolution thereof. Said pawl F of the hourlever has a spur, F Figs. 2 and 3, which projects laterally therefrom in the direction of the adjacent day-wheel ratchet D,and is of sufficient length to overlap the same, so that when 5 the pawl enters the sunken tooth H of said hour-wheel ratchet its spur engages with the day-wheel ratchet and advances the latter to the extent of one tooth in the next ensuing motion of the pawl. By this construction the retype-wheels are adapted to record upon a tape traveling in the plane of said wheels the day and hour and intervals of five minutes, as shown in Fig. 7, in which the initial T indicates one half of a day and the mark the r 5 other half of the same day, the fourteen teeth of the day-wheel ratchet D permitting it to be shifted twice in each day of a week, while the twelve teeth of the hour and minute wheel ratchets permit the same to be shifted once every hour and five minutes, respectively.

The letter L indicates a bed or platen arranged beneath the type-wheels D H M upon a lever, P, whereby it may be reciprocated toward and from said wheels for the purpose of striking a tape to be drawn over the platen in the plane of the type-wheels against the faces thereof, th us producing the desired impression. Between the faces of the platen L and typewheels is interposed an inking-ribbo LQ, Fig.

1, having its ends connected to spools Q, on which it is alternately wound and unwound, and which may be arranged to revolve automatically for shifting the ribbon after each impression. Adjacent to the impressionlever P is a reel, S, for receiving the printed tape, the shaft S of which carries a ratchet, S Fig. 1, to which an intermittingly-revolving motion is imparted by a pawl, S of the impressionlever, causing the tape to be automatically wound on the reel and thereby advanced after each impression.

The impression-lever P has its fulcrum in a shaft, 1?, and it is provided with a returnspring, Phwhile to a proper portion thereof is 5 attached the armature Tof an electrdmagnet, T, so that when the latter is vitalized said lever is actuated by the attraction of the armature. The impression-lever may, however, be actuated by mechanical means-as, for example,

by a key to be rotated on a suitable spindle in proper relation to said lever-and in that event the electro-magnet may be omitted.

The letter U, Figs. 2 and 3, indicates astrip of metal forming an electric switch,one end of which is connected to the center shaft-,0, of the clock-movement, as by a collar fitted thereon, in such a manner that the switch shares the motion of said shaft, causing its outer or free end to travel in a circular plane. Surrounding the center shaft, 0, is a series of insulated contact-pieces, U, forming a switch-dial, each of which pieces is adapted to connect with an electric wire, as by means of a screw, U the whole being inclosed in an insulated casing,U

which is suitably attached to the clock-frame.

The free end of the traveling switch U impinges against the contact-pieces U, and the number of said pieces is in fixed relation to the minutes of ti me, there being in this example six pieces, each representing ten minutes.

When the apparatus is to be applied to use, the switch U, together with the center shaft, 0, is electrically connected with one pole ofa battery, as by a wire, 10, Fig. 8, the other pole of which battery is connected with the magnet T, as by a wire, 11, and the magnet is connected with the several stations to be visited by the watchman, as by a wire, 12, while each of said stations is also connected with one of the contact-pieces U of the switch-dial, as by a wire, 13, so that an electric circuit may be closed by the watchman from the proper station to any one of said contact-pieces through one of the wires, 13, and thence to the magnet T through the switch U, the center shaft, 0 and the' wires 1O 11, whereby the magnet is vitalized, causing the impression-lever P to be actuated for printing the tape. The electric circuit, however, can be closed only during the time that the switch U is in contact with the piece U connected with the station at which the watchman is present, and hence the apparatus is operative to the watchman from that station only within a certain interval of time.
